SPECIFICATION forming part of Letters Patent No. 33 L955, dated January26, 1886.

Application filed January 30, 1884. Serial No. 119,177. (No model.)

To all whom it may concern Be it known that 1, WILLIAM KooH, of thecity, county, and State of New York, have invented a new and usefulImprovement in Quilting-Machines; and I declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying sheets of drawings, forming part of this specification.

This invention is in the nature of an improvement in quilting-machines;and the invention consists, essentially, of vertically'reciprocatingneedle-bars with a series of needles arranged in three rows, theintermediate row having twice as many needles as the first and thirdrows, with. mechanism by which the fabric is fed forward andsimultaneously in a lateral direction, and the mechanism hereinafterparticularly described for operating the shuttles, and the mechanism fordriving or operating the machine.

The invention also consists in the construction of the needle-bar, inwhich three rows of needles are arranged, the intermediate row havingtwice as many needles as the first and third rows, the needles in themiddle row being located diagonally in line with and equidistant fromthe needles of the first and third rows, all the needles being supportedby suitable parallel needle-bars, two of said bars being provided withopenings, whereby the setscrews which hold the needles may be regulated.

In the accompanying sheet of drawings, Figure 1 is a plan or top view ofmy machine, partly in section. Fig. 2 is a front elevation of themachine, partly in section. Fig. 3 is a detailed View of the mechanismfor operating the lateral movement of the carriage. Fig. 4 is an endView of the machine, showing feedratchet and pawls. Fig. 5is averticalsection taken in the line 00 00, Fig. 2, showing shuttlerace andmechanism for operating the shuttle. Fig. 6 is a vertical section of theshuttle-race in the plane of line 2 2, Fig. 5, looking to the left andomitting the rods shown in section in said figure. Fig. 7 is a sideelevation of needle-bar. Fig. 8 is a horizontal section of needle-bars,needles, and set-screw openings, showing the position of the needles andapplication of key for adjusting set-screws of same.

Fig. 9 is a vertical section of needle-bars. Fig. 10 is a plan ordiagram showingone form of stitching made by the needles.

Similar letters of reference indicate like parts in the several figures.

My invention relates to a quilting-machine of. the ordinary typethat is,a machinehaving the Well-known lateral reciprocating motion imparted toits bed or carriage in addition to the common vertical reciprocatingmotion of its needlebar; and the essential fea tures of the inventionconsist in combining with such a quilting machine needle-bars to whichare fixed a series of needles arranged in three distinct rows, one rowbehind the other, the middle row containing twice as manyneedles aseither the first or third rows, which needles are diagonally in linewith and equidistant from each other.

In the construction of my machine a series of organized sewingmechanisms are arranged with a carriage, A, constructed to movehorizontally or to have a horizontal reciprocating motion on thesupporting-frame B. This horizontal reciprocating 'motion is imparted bya name, which, as it revolves alternately, brings its greater and lesserdiameter in contact with rollers b and b, the revolving motion of thecam being imparted by or through a wormwheel, s,- but the reciprocatingof the carriage may be accomplished in any other desirable manner.

To the frame B are fixed uprights B, which support brackets B, throughwhich the verti cal reciprocating bars 0 of the needle-bars D D D work.

(I is a rock-shaft connected with and rocked from the main shaft E bymeans ofthe cranks e and g on said shafts d and E, respectively, andtheir connecting-rod f.

The bars 0, carrying the needle-bars,receive a vertical reciprocatingmotion from the rockshaft (1 by means of the cranks o '0 12 fast onshaft d, and the links 8 s s jointed to the bars a.

The needle-bars D D D which are secured to the lower ends of thereciprocating bars a, consist of three bars, D D D", placed parallel andbehind each other, and extending from one reciprocating bar a to theother. These needle-bars are fixed so as to have a small space,

h, between them, and the first and second I bars,D and D,are providedwith perforations Z, every other perforation in one bar being coincidentwith a-perforation in the other bar. To the needlebars are fixed,bymeans of ordinary set-screws, m, the needles at. These needles in theneedle-bar are so fixed that there 1 shall be three distinct rows ofneedles, one behind the other, the middle bar containing twice as manyneedles as the first and third rows, and the needles of the middle roware diagonally in line with each ofthe outer rows of needles andequidistant from the same.

The machine is provided with a feed-roll, F, and asmoothing or frictionroll, G, which roll F revolves with an intermittent motion by means ofone or more ratchet-wheels, 0, fixed to the outer end or ends of saidfeed-roll F, rotated tooth by tooth by pawls p, as will preszo entlyappear, the smoothing-rollG revolving by the friction of the cloth as itpasses beneath it. The roll G is supported in rock-arms G, held up bysprings G,to press the said roll on roll F, or it may be otherwiseyieldingly held 2 in any well-known way.

The machine is provided with a presser-foot, H, which presser footextends continuously across the width of the machine beneath theneedles, it being perforated to permit the neodles to pass through it,and it is connected with the shaft (1 by connecting bars q and cranks r,as is shown in Fig. 2.

The shuttles and shuttle-races are arranged below the cloth-plate, andare made to corre- 5 spond with the position of the needles. Each.shuttle-race consists of a raceway,I, composed of two parallel bars ofmetal, t, fixed to supports a, at suitable distances apart, to receivethe shuttle, the inner faces of each of these parallel bars being formedof such shape as will allow the shuttle to be received snugly betweenthe bars 1. The base of each bart has formed in it,in the direction ofits length, a rabbet or groove, 1), so that when the bars 15 are placedin position on the supports a, one rabbet or groove, '0, will open intothe space between the two bars 5. into these rabbets or groovesc isfitted the edge of the head to of a stem, at, which stem orshuttle-carrier is provided at its head with a hook, y, and at itsopposite end with a pin-hole, a. This stem has also on its upper surfaceprojections c, to receive the shuttle c and by means of the pinholebefore mentioned is fixed a bar, d, which bar extends across the widthof the machine, and to this bar (1, by means of a link, 6, a crank, f,and a shaft, 9, crank it, and conneeting-rod i, the last-named rod t"being strapped eccentrically to the shaft E, a reciprocating motion isgiven, and this bar gives a corresponding motion to the stem 00, whichin turn carries with like motion the several shuttles beneath theneedles.

Now, when my quilting-machine is con- .65 structed substantially ashereinbefore described, its operation is as follows: The fabric to bequilted is passed over the cloth-plate of the machine, and motion isimparted to the driving-shaft E, and as the. shaft is revolved by meansof its worm s and worm-wheel t, shaft j, and gear-wheels k, Z, and m, arevolving motion through an intermediate shaft, n, is imparted to thecam 01-, so that as the cam alternately brings its greater and lesserdiameter in contact with the rollers b and b, the carriage A has givento it,through a connecting-bar, 0, a reciprocating horizontal motion onthe supporting-frame B of the machine. As this driving-shaft E continuesto revolve by means of a cam, 12, fixed to that shaft,and a slidingblock, q, the pawlsp give an intermittent motion to the ratchet wheel orwheels 0, causing the feed-roll'F to revolve with a like intermittentmotion. The block q is returned after the operation of the earn by meansof a spring, 10 acting against a pin, p, on the said block, andprojecting through a slot in the block-holder q". The upper pawl, p, isalso spring-pressed; but it may serve simply as a detent. Thisdriving-shaft Estill continues to revolve through or by means of thewrist-pin g and the connectingrod f and crank e. A partial rotary orrocking motion is given to the shaft 01, and as this shaft d is in thisway rocked through or by means of cranks v v if, fixed to it andconnecting-rods s, 3 and s, the bars 0 are caused to reciprocatevertically, and with this motion alternately carry upward and downwardthe needle-bars D D D and also through or by means of cranks r and r andsuitable connecting-bars q q, fixed to the rocking shaft d, move upwardand downward with a reciprocating motion the presser-foot H.

The several parts of the mechanism of the machine being now in motion,as described, the fabricto be quilted is drawn or fed by the operationof the feedroll F beneath the needles n, the presser-foot H pressing thefabric closely upon the surface of the cloth-plate until the needleshave passed through the fabric to form the stitches, the smoothing orfriction roller G keeping the fabric smooth and assisting thefeed-roller to bite the surface of the fabric, and as the needlesdescend the shuttles, operating in the manner hereinbefore described,pass through the loops of the thread making the lock-stitch. Now, itwill be seen that since the needles n are arranged in a series of threerows, and so that the needles of the middle row are diagonally in linewith the needles of the first and third rows, and that as these needlesare moving up and down in a vertical direction simultaneously with thelateral reciprocating motion of the carriage of 1'25 the machine,diagonal lines of stitches are formed in the material to be quilted. Bythe lateral motion of the carriage in opposite directions, the directionof the diagonal lines of stitches is reversed, whereby each needleproduces a zigzag line of stitches, which meets the zigzag lines ofstitches of the adjoining needles at the angles of said needles, so asto impart thereby to the fabric the character of intercrossing diagonallines of stitches that form regular diamonds, as is shown in Fig. 10 ofthe drawings.

It will be observed that by reason of the intermittent revolving motionof the feed-roll F the feeding of the fabric beneath the needles ceasesat the instant the needles enter the fabric, and is resumed the instantthe needles clear the fabric in their upward movement.

In Fig. 3 I have shown an arrangement of gearing for varying the speedof the carriagereciprocating mechanism. The pinions h and m are mountedon their shaftsj and n, and on shaftj, I hang an arm, Z in one end ofwhich is a longitudinal slot, Z, in which is adjustably secured a bolt,Z, which serves as the pin or nib on which the idler'pinion l revolves.The lower end of the arm Z is slotted, Z transversely in an arc of acircle, and is secured to the frame B thereat by a set-screw, Z. Bythese means idler-pinions Z of difl'erent diameter may be interposedbetween the pinions h and m to vary the speed of the latter.

When it is desired to change the form or character of the lines ofstitching produced by the needles, this may be accomplished by substituting larger or smaller wheels for the gearwheels Z, suchsubstitution resultingin increasing or diminishing the extent of thehorizontal reciprocating throw of the carriage A, so that the point orpoints at which the stitching of each needle crosses the stitching ofthe other needle, or rather the angle at which such cross ing takesplace, will be increased or lessened, and thereby produce correspondingchanges in the form or design of the stitching on the fabric, and anumber of different designs or variegated effects can be produced in aquick, economical, and effective manner by the con- 0 joined action ofthe mechanism hereinbefore described for moving the fabric, and theaction of the needlebars having three independent rows of needles. Sincethe three rows of needles are arranged one row behind the other, itwould be difficult to remove, replace, or tighten the needles in therearmost rows, unless some provision were made for that purpose, and tothat end the perforations Z are formed in the first and middleneedle-bars, so that through these perforations a key, L, can be passedand the set-screws m of the needles be reached for the purpose oftightening or slackening them, as the exigency may require.

The thread-takeup mechanism and the mechanism for beaming the fabric asit is quilted are shown, and may be of usual construction, and form,with other parts shown but not described, no part of this invention.

I hereby reserve for my application Serial No. 176,373, filed September7, 1885, the claims for the shuttle race and carrier herein shown, butnot claimed. At the same time I direct attention to my Patent No.323,584, dated August 4, 1885, the application for which was filedMay20, 1885, as covering one specific form of my invention inshuttle-carriers.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a quilting-machine, the combination of a vertically-reciprocatingneedlebar having a series of needles arranged in three rows, one behindthe other, the intermediate row having twice as many needles as thefirst or third row, the needles of said intermediate row being set in adiagonal line with and equidistant from the needles of the first andthird rows, devices for feeding the fabric forward beneath the needles,and mechanism whereby laterally-reciprocating motion is imparted to theentire sewing mechanisms, substantially as set forth.

2. In a quilting-machine, a needlebar constructed with three rows ofneedles, one behind the other, the intermediate row having twice as manyneedles as the first and third row, which needles are located in adiagonal line with and equidistant from the needles of the first andthird rows, substantially as specified, in combination with means foroperating the needle-bar.

3. In a quiltingmachine with two or more parallel need1e bars andneedles fixed thereto, a series of openings in the needle-bars, wherebythe set-screws of the rearmost needle-bars may be adjusted, as and forthe purpose described.
